I have to say Yoshida's Legendary Equipment concept is quite intriguing. Instead of making it a concept where said gear could be outdated he instead makes it where the equipment you obtain and the materia on your gear will help you in obtaining it. Though I can't imagine it will be easy but that's the point of it.

Imagine during these seasonal times the price of materia will rise as well as the price of mending those materias to the weapon/armor lol.
